WHIFFLETREE-HANGER.

Specification of Letters Patent.

Patented Auge. 30, 1910.

Application led November 26, 1909. 'Serial No. 529,980.

To all rwhom 'it may concern:

Be it known that I, JOHN I. SHAW, a citizen of the United States,residing at N ovinger, vin the county of Adair and State of Missouri,have invented a new and useful WhifHetree-Hanger, of which the followingis a specication.

This invention relates to devices for coup ling double trees upon awagon pole and swingle trees upon shaft cross bars, and has for anobject to provide a hanger that will permit of a swivel movement of theswingle or double tree upon the cross bar or wagon pole While holdingthe same against tilting or rocking movement.

A further object is to provide a device of this character that will beadjustable to receive any ordinary swingle or double tree.

A still further object is to provide a device of this character thatwill have an adjustable base plate which may be adjusted from time totime to take up the wear upon the parts.

With the above advantages and other objects in view which will appear asthe description proceeds, my invention embraces certain novel details ofconstruction and combination of parts which will be hereinafter morefully described and claimed.

In the accompanying drawing forming part of this specification, Figure 1is a perspective view of my improved hanger in applied position. Fig. 2is a transverse sectional view through the hanger showing the framemember of the device in elevation and disposed in a plane at rightangles to the vehicle pole. Fig. 3 is a transverse sectional view takenon the line A B of Fi 2 with parts removed. Fig. 4 is a longitudinalsectional view of the hanger taken on the line C-D of Fig. 2: Fig. 5 isan underneath plan view of the frame supporting disk. Fig. 6 is aperspective view of a modiication of my improved hanger. Fig. 7 is alongitudinal sectional view of the hanger with parts in elevation andparts broken away. Fig. 8 is a transverse sectional view through theline E-F of Fig. 7. Fig. 9 is a fragmentary sectional view taken on theline G-II of Fig. 7

Like characters of reference designate similar parts in the views shown.

Referring to the drawing, 5 designates a vehicle pole and 6 a doubletree, both of the usual and well known kind.

The hanger for coupling the double tree to the vehicle pole comprises anadjustable base plate consisting of a pair of semi-circular plates 7each having an arm 8 projecting from its outer periphery. Formed in thearms 8 are longitudinal slots 9 to receive securing screws or bolts 10.The slots 9 are of a size to slidingly fit the shanks of the securingbolts so that the plates 7 may be slid longitudinally of the pole andtheir opposed terminals drawn closer together from time to time to takeup the wear of the movable members upon the plates and maintain a truebearing between the two at all times. Mounted between the semi-circularplates is a circular disk 11 having its top face recessed to receive thehead of a bolt 12 which passes through the pole 5 and rigidly securesthe disk thereto. The bottom face of the disk is provided with aplurality of radial corrugations 13 adapted to impinge against the poleand prevent the independent rotation of the disk. Formed upon the diskis an annular flange 14 which extends beyond the periphery of the diskand retains in position a ring` l5. The ring 15 is rotatably mountedbetween the diski and semi-circular plates and 'is provided with alaterally extending flange 16 which slidingly engages the bottom face ofthe llange 14 and opposed faces of the disk and semi-circular plates, asshown in Fig. 2. The top face of the ring is flush with the top face ofthe disk and cooperates with the latter to support the double tree 6.'

Rigidly secured to the top face of the ring 15 is a U-shaped frame, thespaced standards 17 of which are expanded at their base, as shown at 18,to enga e and extend beyond the top face of the a jacent clamping plate7 so that a true bearing between the two is maintained should thesemi-circular plate become loosened on its supporting screw 10.Threading through the intermediate portion of the vcross bar 19 of theUshaped frame is a feed screw 20, the extremity of which engages aclamping plate 21, which latter is adapted to snugly engage the opposedface of the double tree 6. The clamping plate 21 is provided at itsextremities with eyes for the reception of clamping bolts 22 which passentirely through the double tree and are rigidly engaged in the ring 15in the bottom face of which latter are formed recesses 23 to receive theheads of the bolts, as shown. The recesses 23 reduce the dead weight ofthe disk and are disposed upon the same side of the center line of thering, as clearly shown in Fig. 5, so that a flat bearing face isprovided upon the opposite side of the center line for contact with theopposed top face of the vehicle pole 5. Extending laterally from thelongitudinal sides of the clamping plate 21 are cross arms 24 havingbifurcated extremities 25 to engage guide strips 26 formed longitudinally of the inner faces of the standards 17.

In -Fig. 6 is shown a modification of my device. In this case 26 and 27designate a vehicle pole and double tree respectively of the usual andwell known kind. The hanger consists of a pair of semi-circular plates28 each having a longitudinally slotted arm 29 extending laterally fromits periphery. Engaged through the longitudinal slot of each arm is asecuring bolt 30 upon the shank of which the arm is slidable so that theopposed terminals of the semi-circular plates may be drawn together fromtime to time to take up thel wear upon the parts, as above described.Mounted upon the top face of the vehicle pole 26 is a circular disk 31,the bottom face of which is serrated, as shown at 32, to prevent theindependent rotation of the disk and the top face of which is re* cessedto receive the head of a bolt 33 which 'passesentirely through thepoleand serves to rigidly secure the disk thereto. Formed upon theperiphery of the disk is a flange 34 which holds a rotary ring 35 inposition, as above described. The rotary ring 35 is provided with alaterally projecting flange 36 to engage the bottom face of the flange34. The top face of the rin terminates flush with the top face of thedisk and cooperates therewith to support the double tree 27. Projectingupwardly from the ring is a frame comprising spaced standards 37, thelower portions of which are expanded, as shown at 38, to form extensionswhich engage and project over the to face of the semi-circular platesand provi e a true bearing between the standards and the plates.

To enable a double tree of any size to be interposed between thestandards 37 one of the standards is provided with a wedgeshaped lockinglug 39 which engages an elongated wedge-shaped recess 40 disposed in thetop face of the ring 35. The stand ard is thus capable of slidingmovement toward or away from the opposite standard to permit of anysized double tree being inserted therebetween.

An arm 41 is provided having its termi nals bent over, and provided witheyes which engage the shanks of the before-mentioned securing bolts 30.'lll'ni'eading through the intermediate portion of the arm 4l is'a feedscrew 42, the terminal of which bears against a clamping plate 43. Theclamping plate is adapted to conform to the contour of the double treeand is provided with laterally extending arms 44 through which screws 45are passed to rigidly hold the clamping member to the double tree.Screws 46 are passed through the clamping plate 43 and standards 37 intothe double tree to cause the above mentioned parts to conform to theoutline of andmsnugly engage the double tree.
